Referring still to FIG. 1A, various components depicted in this figurewill now be described in more detail. Regarding the wirelesscommunication unit 110, the broadcast receiving module 111 is typicallyconfigured to receive a broadcast signal and/or broadcast associatedinformation from an external broadcast managing entity via a broadcastchannel. The broadcast channel may include a satellite channel, aterrestrial channel, or both. In some embodiments, two or more broadcastreceiving modules 111 may be utilized to facilitate simultaneouslyreceiving of two or more broadcast channels, or to support switchingamong broadcast channels.

system which generates and transmits a broadcast signal and/or broadcastassociated information, or a server which receives a pre-generatedbroadcast signal and/or broadcast associated information, and sends suchitems to the mobile terminal. The broadcast signal may be implementedusing any of a TV broadcast signal, a radio broadcast signal, a databroadcast signal, and combinations thereof, among others. The broadcastsignal in some cases may further include a data broadcast signalcombined with a TV or radio broadcast signal.

The broadcast signal may be encoded according to any of a variety oftechnical standards or broadcasting methods (for example, InternationalOrganization for Standardization (ISO), International ElectrotechnicalCommission (IEC), Digital Video Broadcast (DVB), Advanced TelevisionSystems Committee (ATSC), and the like) for transmission and receptionof digital broadcast signals. The broadcast receiving module 111 canreceive the digital broadcast signals using a method appropriate for thetransmission method utilized.

Examples of broadcast associated information may include informationassociated with a broadcast channel, a broadcast program, a broadcastevent, a broadcast service provider, or the like. The broadcastassociated information may also be provided via a mobile communicationnetwork, and in this case, received by the mobile communication module112.

The broadcast associated information may be implemented in variousformats. For instance, broadcast associated information may include anElectronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB),an Electronic Service Guide (ESG) of Digital Video Broadcast-Handheld(DVB-H), and the like. Broadcast signals and/or broadcast associatedinformation received via the broadcast receiving module 111 may bestored in a suitable device, such as a memory 170.

The mobile communication module 112 can transmit and/or receive wirelesssignals to and from one or more network entities. Typical examples of anetwork entity include a base station, an external mobile terminal, aserver, and the like. Such network entities form part of a mobilecommunication network, which is constructed according to technicalstandards or communication methods for mobile communications (forexample, Global System for Mobile Communication (GSM), Code DivisionMulti Access (CDMA), CDMA2000 (Code Division Multi Access 2000), EV-DO(Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), WidebandCDMA (WCDMA), High Speed Downlink Packet access (HSDPA), HSUPA (HighSpeed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long TermEvolution-Advanced), and the like).

One example of thewireless area networks is a wireless personal area networks.

In some embodiments, another mobile terminal (which may be configuredsimilarly to mobile terminal 100) may be a wearable device, for example,a smart watch, a smart glass or a head mounted display (HMD), which isable to exchange data with the mobile terminal 100 (or otherwisecooperate with the mobile terminal 100). The short-range communicationmodule 114 may sense or recognize the wearable device, and permitcommunication between the wearable device and the mobile terminal 100.In addition, when the sensed wearable device is a device which isauthenticated to communicate with the mobile terminal 100, thecontroller 180, for example, may cause transmission of data processed inthe mobile terminal 100 to the wearable device via the short-rangecommunication module 114. Hence, a user of the wearable device may usethe data processed in the mobile terminal 100 on the wearable device.For example, when a call is received in the mobile terminal 100, theuser may answer the call using the wearable device. Also, when a messageis received in the mobile terminal 100, the user can check the receivedmessage using the wearable device.

The location information module 115 is generally configured to detect,calculate, derive or otherwise identify a position of the mobileterminal. As an example, the location information module 115 includes aGlobal Position System (GPS) module, a Wi-Fi module, or both. Ifdesired, the location information module 115 may alternatively oradditionally function with any of the other modules of the wirelesscommunication unit 110 to obtain data related to the position of themobile terminal.

As one example, when the mobile terminal uses a GPS module, a positionof the mobile terminal may be acquired using a signal sent from a GPSsatellite. As another example, when the mobile terminal uses the Wi-Fimodule, a position of the mobile terminal can be acquired based oninformation related to a wireless access point (AP) which transmits orreceives a wireless signal to or from the Wi-Fi module.

The input unit 120 may be configured to permit various types of input tothe mobile terminal 120. Examples of such input include audio, image,video, data, and user input. Image and video input is often obtainedusing one or more cameras 121. Such cameras 121 may process image framesof still pictures or video obtained by image sensors in a video or imagecapture mode. The processed image frames can be displayed on the displayunit 151 or stored in memory 170. In some cases, the cameras 121 may bearranged in a matrix configuration to permit a plurality of imageshaving various angles or focal points to be input to the mobile terminal100. As another example, the cameras 121 may be located in astereoscopic arrangement to acquire left and right images forimplementing a stereoscopic image.

The microphone 122 is generally implemented to permit audio input to themobile terminal 100. The audio input can be processed in various mannersaccording to a function being executed in the mobile terminal 100. Ifdesired, the microphone 122 may include assorted noise removingalgorithms to remove unwanted noise generated in the course of receivingthe external audio.

The user input unit 123 is a component that permits input by a user.Such user input may enable the controller 180 to control operation ofthe mobile terminal 100. The user input unit 123 may include one or moreof a mechanical input element (for example, a key, a button located on afront and/or rear surface or a side surface of the mobile terminal 100,a dome switch, a jog wheel, a jog switch, and the like), or atouch-sensitive input, among others. As one example, the touch-sensitiveinput may be a virtual key or a soft key, which is displayed on a touchscreen through software processing, or a touch key which is located onthe mobile terminal at a location that is other than the touch screen.On the other hand, the virtual key or the visual key may be displayed onthe touch screen in various shapes, for example, graphic, text, icon,video, or a combination thereof.

The sensing unit 140 is generally configured to sense one or more ofinternal information of the mobile terminal, surrounding environmentinformation of the mobile terminal, user information, or the like. Thecontroller 180 generally cooperates with the sending unit 140 to controloperation of the mobile terminal 100 or execute data processing, afunction or an operation associated with an application programinstalled in the mobile terminal based on the sensing provided by thesensing unit 140. The sensing unit 140 may be implemented using any of avariety of sensors, some of which will now be described in more detail.

The proximity sensor 141 may include a sensor to sense presence orabsence of an object approaching a surface, or an object located near asurface, by using an electromagnetic field, infrared rays, or the likewithout a mechanical contact. The proximity sensor 141 may be arrangedat an inner region of the mobile terminal covered by the touch screen,or near the touch screen.

The proximity sensor 141, for example, may include any of a transmissivetype photoelectric sensor, a direct reflective type photoelectricsensor, a mirror reflective type photoelectric sensor, a high-frequencyoscillation proximity sensor, a capacitance type proximity sensor, amagnetic type proximity sensor, an infrared rays proximity sensor, andthe like. When the touch screen is implemented as a capacitance type,the proximity sensor 141 can sense proximity of a pointer relative tothe touch screen by changes of an electromagnetic field, which isresponsive to an approach of an object with conductivity. In this case,the touch screen (touch sensor) may also be categorized as a proximitysensor.

The term “proximity touch” will often be referred to herein to denotethe scenario in which a pointer is positioned to be proximate to thetouch screen without contacting the touch screen. The term “contacttouch” will often be referred to herein to denote the scenario in whicha pointer makes physical contact with the touch screen. For the positioncorresponding to the proximity touch of the pointer relative to thetouch screen, such position will correspond to a position where thepointer is perpendicular to the touch screen. The proximity sensor 141may sense proximity touch, and proximity touch patterns (for example,distance, direction, speed, time, position, moving status, and thelike).

In general, controller 180 processes data corresponding to proximitytouches and proximity touch patterns sensed by the proximity sensor 141,and cause output of visual information on the touch screen. In addition,the controller 180 can control the mobile terminal 100 to executedifferent operations or process different data according to whether atouch with respect to a point on the touch screen is either a proximitytouch or a contact touch.

A touch sensor can sense a touch applied to the touch screen, such asdisplay unit 151, using any of a variety of touch methods. Examples ofsuch touch methods include a resistive type, a capacitive type, aninfrared type, and a magnetic field type, among others.

As one example, the touch sensor may be configured to convert changes ofpressure applied to a specific part of the display unit 151, or convertcapacitance occurring at a specific part of the display unit 151, intoelectric input signals. The touch sensor may also be configured to sensenot only a touched position and a touched area, but also touch pressureand/or touch capacitance. A touch object is generally used to apply atouch input to the touch sensor. Examples of typical touch objectsinclude a finger, a touch pen, a stylus pen, a pointer, or the like.

When a touch input is sensed by a touch sensor, corresponding signalsmay be transmitted to a touch controller. The touch controller mayprocess the received signals, and then transmit corresponding data tothe controller 180. Accordingly, the controller 180 may sense whichregion of the display unit 151 has been touched. Here, the touchcontroller may be a component separate from the controller 180, thecontroller 180, and combinations thereof.

In some embodiments, the controller 180 may execute the same ordifferent controls according to a type of touch object that touches thetouch screen or a touch key provided in addition to the touch screen.Whether to execute the same or different control according to the objectwhich provides a touch input may be decided based on a current operatingstate of the mobile terminal 100 or a currently executed applicationprogram, for example.

The touch sensor and the proximity sensor may be implementedindividually, or in combination, to sense various types of touches. Suchtouches includes a short (or tap) touch, a long touch, a multi-touch, adrag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipetouch, a hovering touch, and the like.

If desired, an ultrasonic sensor may be implemented to recognizeposition information relating to a touch object using ultrasonic waves.The controller 180, for example, may calculate a position of a wavegeneration source based on information sensed by an illumination sensorand a plurality of ultrasonic sensors. Since light is much faster thanultrasonic waves, the time for which the light reaches the opticalsensor is much shorter than the time for which the ultrasonic wavereaches the ultrasonic sensor. The position of the wave generationsource may be calculated using this fact. For instance, the position ofthe wave generation source may be calculated using the time differencefrom the time that the ultrasonic wave reaches the sensor based on thelight as a reference signal.

The camera 121 typically includes at least one a camera sensor (CCD,CMOS etc.), a photo sensor (or image sensors), and a laser sensor.

Implementing the camera 121 with a laser sensor may allow detection of atouch of a physical object with respect to a 3D stereoscopic image. Thephoto sensor may be laminated on, or overlapped with, the displaydevice. The photo sensor may be configured to scan movement of thephysical object in proximity to the touch screen. In more detail, thephoto sensor may include photo diodes and transistors at rows andcolumns to scan content received at the photo sensor using an electricalsignal which changes according to the quantity of applied light. Namely,the photo sensor may calculate the coordinates of the physical objectaccording to variation of light to thus obtain position information ofthe physical object.

The display unit 151 is generally configured to output informationprocessed in the mobile terminal 100. For example, the display unit 151may display execution screen information of an application programexecuting at the mobile terminal 100 or user interface (UI) and graphicuser interface (GUI) information in response to the execution screeninformation.

In some embodiments, the display unit 151 may be implemented as astereoscopic display unit for displaying stereoscopic images. A typicalstereoscopic display unit may employ a stereoscopic display scheme suchas a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme(glassless scheme), a projection scheme (holographic scheme), or thelike.

In general, a 3D stereoscopic image may include a left image (e.g., aleft eye image) and a right image (e.g., a right eye image). Accordingto how left and right images are combined into a 3D stereoscopic image,a 3D stereoscopic imaging method can be divided into a top-down methodin which left and right images are located up and down in a frame, anL-to-R (left-to-right or side by side) method in which left and rightimages are located left and right in a frame, a checker board method inwhich fragments of left and right images are located in a tile form, aninterlaced method in which left and right images are alternately locatedby columns or rows, and a time sequential (or frame by frame) method inwhich left and right images are alternately displayed on a time basis.

Also, as for a 3D thumbnail image, a left image thumbnail and a rightimage thumbnail can be generated from a left image and a right image ofan original image frame, respectively, and then combined to generate asingle 3D thumbnail image. In general, the term “thumbnail” may be usedto refer to a reduced image or a reduced still image. A generated leftimage thumbnail and right image thumbnail may be displayed with ahorizontal distance difference there between by a depth corresponding tothe disparity between the left image and the right image on the screen,thereby providing a stereoscopic space sense.

A left image and a right image required for implementing a 3Dstereoscopic image may be displayed on the stereoscopic display unitusing a stereoscopic processing unit. The stereoscopic processing unitcan receive the 3D image and extract the left image and the right image,or can receive the 2D image and change it into a left image and a rightimage.

The audio output module 152 is generally configured to output audiodata. Such audio data may be obtained from any of a number of differentsources, such that the audio data may be received from the wirelesscommunication unit 110 or may have been stored in the memory 170. Theaudio data may be output during modes such as a signal reception mode, acall mode, a record mode, a voice recognition mode, a broadcastreception mode, and the like. The audio output module 152 can provideaudible output related to a particular function (e.g., a call signalreception sound, a message reception sound, etc.) performed by themobile terminal 100. The audio output module 152 may also be implementedas a receiver, a speaker, a buzzer, or the like.

A haptic module 153 can be configured to generate various tactileeffects that a user feels, perceive, or otherwise experience. A typicalexample of a tactile effect generated by the haptic module 153 isvibration. The strength, pattern and the like of the vibration generatedby the haptic module 153 can be controlled by user selection or settingby the controller. For example, the haptic module 153 may outputdifferent vibrations in a combining manner or a sequential manner.

Besides vibration, the haptic module 153 can generate various othertactile effects, including an effect by stimulation such as a pinarrangement vertically moving to contact skin, a spray force or suctionforce of air through a jet orifice or a suction opening, a touch to theskin, a contact of an electrode, electrostatic force, an effect byreproducing the sense of cold and warmth using an element that canabsorb or generate heat, and the like.

The haptic module 153 can also be implemented to allow the user to feela tactile effect through a muscle sensation such as the user's fingersor arm, as well as transferring the tactile effect through directcontact. Two or more haptic modules 153 may be provided according to theparticular configuration of the mobile terminal 100.

An optical output module 154 can output a signal for indicating an eventgeneration using light of a light source. Examples of events generatedin the mobile terminal 100 may include message reception, call signalreception, a missed call, an alarm, a schedule notice, an emailreception, information reception through an application, and the like.

A signal output by the optical output module 154 may be implemented insuch a manner that the mobile terminal emits monochromatic light orlight with a plurality of colors. The signal output may be terminated asthe mobile terminal senses that a user has checked the generated event,for example.

The interface unit 160 serves as an interface for external devices to beconnected with the mobile terminal 100. For example, the interface unit160 can receive data transmitted from an external device, receive powerto transfer to elements and components within the mobile terminal 100,or transmit internal data of the mobile terminal 100 to such externaldevice. The interface unit 160 may include wired or wireless headsetports, external power supply ports, wired or wireless data ports, memorycard ports, ports for connecting a device having an identificationmodule, audio input/output (I/O) ports, video I/O ports, earphone ports,or the like.

The identification module may be a chip that stores various informationfor authenticating authority of using the mobile terminal 100 and mayinclude a user identity module (UIM), a subscriber identity module(SIM), a universal subscriber identity module (USIM), and the like. Inaddition, the device having the identification module (also referred toherein as an “identifying device”) may take the form of a smart card.Accordingly, the identifying device can be connected with the terminal100 via the interface unit 160.

When the mobile terminal 100 is connected with an external cradle, theinterface unit 160 can serve as a passage to allow power from the cradleto be supplied to the mobile terminal 100 or may serve as a passage toallow various command signals input by the user from the cradle to betransferred to the mobile terminal there through. Various commandsignals or power input from the cradle may operate as signals forrecognizing that the mobile terminal is properly mounted on the cradle.

The memory 170 can store programs to support operations of thecontroller 180 and store input/output data (for example, phonebook,messages, still images, videos, etc.). The memory 170 may store datarelated to various patterns of vibrations and audio which are output inresponse to touch inputs on the touch screen.

The memory 170 may include one or more types of storage mediumsincluding a Flash memory, a hard disk, a solid state disk, a silicondisk, a multimedia card micro type, a card-type memory (e.g., SD or DXmemory, etc), a Random Access Memory (RAM), a Static Random AccessMemory (SRAM), a Read-Only Memory (ROM), an Electrically ErasableProgrammable Read-Only Memory (EEPROM), a Programmable Read-Only memory(PROM), a magnetic memory, a magnetic disk, an optical disk, and thelike. The mobile terminal 100 may also be operated in relation to anetwork storage device that performs the storage function of the memory170 over a network, such as the Internet.

The controller 180 may typically control the general operations of themobile terminal 100. For example, the controller 180 may set or releasea lock state for restricting a user from inputting a control commandwith respect to applications when a status of the mobile terminal meetsa preset condition.

The controller 180 can also perform the controlling and processingassociated with voice calls, data communications, video calls, and thelike, or perform pattern recognition processing to recognize ahandwriting input or a picture drawing input performed on the touchscreen as characters or images, respectively. In addition, thecontroller 180 can control one or a combination of those components inorder to implement various exemplary embodiments disclosed herein.

The power supply unit 190 receives external power or provide internalpower and supply the appropriate power required for operating respectiveelements and components included in the mobile terminal 100. The powersupply unit 190 may include a battery, which is typically rechargeableor be detachably coupled to the terminal body for charging.

The power supply unit 190 may include a connection port. The connectionport may be configured as one example of the interface unit 160 to whichan external charger for supplying power to recharge the battery iselectrically connected.

As another example, the power supply unit 190 may be configured torecharge the battery in a wireless manner without use of the connectionport. In this example, the power supply unit 190 can receive power,transferred from an external wireless power transmitter, using at leastone of an inductive coupling method which is based on magnetic inductionor a magnetic resonance coupling method which is based onelectromagnetic resonance.

Various embodiments described herein may be implemented in acomputer-readable medium, a machine-readable medium, or similar mediumusing, for example, software, hardware, or any combination thereof.

Referring now to FIGS. 1B and 1C, the mobile terminal 100 is describedwith reference to a bar-type terminal body. However, the mobile terminal100 may alternatively be implemented in any of a variety of differentconfigurations. Examples of such configurations include watch-type,clip-type, glasses-type, or as a folder-type, flip-type, slide-type,swing-type, and swivel-type in which two and more bodies are combinedwith each other in a relatively movable manner, and combinationsthereof. Discussion herein will often relate to a particular type ofmobile terminal (for example, bar-type, watch-type, glasses-type, andthe like). However, such teachings with regard to a particular type ofmobile terminal will generally apply to other types of mobile terminalsas well.

The mobile terminal 100 will generally include a case (for example,frame, housing, cover, and the like) forming the appearance of theterminal. In this embodiment, the case is formed using a front case 101and a rear case 102. Various electronic components are incorporated intoa space formed between the front case 101 and the rear case 102. Atleast one middle case may be additionally positioned between the frontcase 101 and the rear case 102.

The display unit 151 is shown located on the front side of the terminalbody to output information. As illustrated, a window 151 a of thedisplay unit 151 may be mounted to the front case 101 to form the frontsurface of the terminal body together with the front case 101.

In some embodiments, electronic components may also be mounted to therear case 102. Examples of such electronic components include adetachable battery 191, an identification module, a memory card, and thelike. Rear cover 103 is shown covering the electronic components, andthis cover may be detachably coupled to the rear case 102. Therefore,when the rear cover 103 is detached from the rear case 102, theelectronic components mounted to the rear case 102 are externallyexposed.

As illustrated, when the rear cover 103 is coupled to the rear case 102,a side surface of the rear case 102 is partially exposed. In some cases,upon the coupling, the rear case 102 may also be completely shielded bythe rear cover 103. In some embodiments, the rear cover 103 may includean opening for externally exposing a camera 121 b or an audio outputmodule 152 b.

The cases 101, 102, 103 may be formed by injection-molding syntheticresin or may be formed of a metal, for example, stainless steel (STS),aluminum (Al), titanium (Ti), or the like.

As an alternative to the example in which the plurality of cases form aninner space for accommodating components, the mobile terminal 100 may beconfigured such that one case forms the inner space. In this example, amobile terminal 100 having a uni-body is formed in such a manner thatsynthetic resin or metal extends from a side surface to a rear surface.

If desired, the mobile terminal 100 may include a waterproofing unit(not shown) for preventing introduction of water into the terminal body.For example, the waterproofing unit may include a waterproofing memberwhich is located between the window 151 a and the front case 101,between the front case 101 and the rear case 102, or between the rearcase 102 and the rear cover 103, to hermetically seal an inner spacewhen those cases are coupled.

FIGS. 1B and 1C depict certain components as arranged on the mobileterminal. However, it is to be understood that alternative arrangementsare possible and within the teachings of the instant disclosure. Somecomponents may be omitted or rearranged. For example, the firstmanipulation unit 123 a may be located on another surface of theterminal body, and the second audio output module 152 b may be locatedon the side surface of the terminal body.

The display unit 151 outputs information processed in the mobileterminal 100. The display unit 151 may be implemented using one or moresuitable display devices. Examples of such suitable display devicesinclude a liquid crystal display (LCD), a thin film transistor-liquidcrystal display (TFT-LCD), an organic light emitting diode (OLED), aflexible display, a 3-dimensional (3D) display, an e-ink display, andcombinations thereof.

The display unit 151 may be implemented using two display devices, whichcan implement the same or different display technology. For instance, aplurality of the display units 151 may be arranged on one side, eitherspaced apart from each other, or these devices may be integrated, orthese devices may be arranged on different surfaces.

The display unit 151 may also include a touch sensor which senses atouch input received at the display unit. When a touch is input to thedisplay unit 151, the touch sensor may be configured to sense this touchand the controller 180, for example, may generate a control command orother signal corresponding to the touch. The content which is input inthe touching manner may be a text or numerical value, or a menu itemwhich can be indicated or designated in various modes.

The touch sensor may be configured in a form of a film having a touchpattern, disposed between the window 151 a and a display on a rearsurface of the window 151 a, or a metal wire which is patterned directlyon the rear surface of the window 151 a. Alternatively, the touch sensormay be integrally formed with the display. For example, the touch sensormay be disposed on a substrate of the display or within the display.

The display unit 151 may also form a touch screen together with thetouch sensor. Here, the touch screen may serve as the user input unit123 (see FIG. 1A). Therefore, the touch screen may replace at least someof the functions of the first manipulation unit 123 a.

The first audio output module 152 a may be implemented in the form of aspeaker to output voice audio, alarm sounds, multimedia audioreproduction, and the like.

The window 151 a of the display unit 151 will typically include anaperture to permit audio generated by the first audio output module 152a to pass. One alternative is to allow audio to be released along anassembly gap between the structural bodies (for example, a gap betweenthe window 151 a and the front case 101). In this case, a holeindependently formed to output audio sounds may not be seen or isotherwise hidden in terms of appearance, thereby further simplifying theappearance and manufacturing of the mobile terminal 100.

The optical output module 154 can be configured to output light forindicating an event generation. Examples of such events include amessage reception, a call signal reception, a missed call, an alarm, aschedule notice, an email reception, information reception through anapplication, and the like. When a user has checked a generated event,the controller can control the optical output unit 154 to stop the lightoutput.

The first camera 121 a can process image frames such as still or movingimages obtained by the image sensor in a capture mode or a video callmode. The processed image frames can then be displayed on the displayunit 151 or stored in the memory 170.

The first and second manipulation units 123 a and 123 b are examples ofthe user input unit 123, which may be manipulated by a user to provideinput to the mobile terminal 100. The first and second manipulationunits 123 a and 123 b may also be commonly referred to as a manipulatingportion, and may employ any tactile method that allows the user toperform manipulation such as touch, push, scroll, or the like. The firstand second manipulation units 123 a and 123 b may also employ anynon-tactile method that allows the user to perform manipulation such asproximity touch, hovering, or the like.

FIG. 1B illustrates the first manipulation unit 123 a as a touch key,but possible alternatives include a mechanical key, a push key, a touchkey, and combinations thereof.

Input received at the first and second manipulation units 123 a and 123b may be used in various ways. For example, the first manipulation unit123 a may be used by the user to provide an input to a menu, home key,cancel, search, or the like, and the second manipulation unit 123 b maybe used by the user to provide an input to control a volume level beingoutput from the first or second audio output modules 152 a or 152 b, toswitch to a touch recognition mode of the display unit 151, or the like.

As another example of the user input unit 123, a rear input unit (notshown) may be located on the rear surface of the terminal body. The rearinput unit can be manipulated by a user to provide input to the mobileterminal 100. The input may be used in a variety of different ways. Forexample, the rear input unit may be used by the user to provide an inputfor power on/off, start, end, scroll, control volume level being outputfrom the first or second audio output modules 152 a or 152 b, switch toa touch recognition mode of the display unit 151, and the like. The rearinput unit may be configured to permit touch input, a push input, orcombinations thereof.

The rear input unit may be located to overlap the display unit 151 ofthe front side in a thickness direction of the terminal body. As oneexample, the rear input unit may be located on an upper end portion ofthe rear side of the terminal body such that a user can easilymanipulate it using a forefinger when the user grabs the terminal bodywith one hand. Alternatively, the rear input unit can be positioned atmost any location of the rear side of the terminal body.

Embodiments that include the rear input unit may implement some or allof the functionality of the first manipulation unit 123 a in the rearinput unit. As such, in situations where the first manipulation unit 123a is omitted from the front side, the display unit 151 can have a largerscreen.

As a further alternative, the mobile terminal 100 may include a fingerscan sensor which scans a user's fingerprint. The controller 180 canthen use fingerprint information sensed by the finger scan sensor aspart of an authentication procedure. The finger scan sensor may also beinstalled in the display unit 151 or implemented in the user input unit123.

The microphone 122 is shown located at an end of the mobile terminal100, but other locations are possible. If desired, multiple microphonesmay be implemented, with such an arrangement permitting the receiving ofstereo sounds.

The interface unit 160 may serve as a path allowing the mobile terminal100 to interface with external devices. For example, the interface unit160 may include one or more of a connection terminal for connecting toanother device (for example, an earphone, an external speaker, or thelike), a port for near field communication (for example, an InfraredData Association (IrDA) port, a Bluetooth port, a wireless LAN port, andthe like), or a power supply terminal for supplying power to the mobileterminal 100. The interface unit 160 may be implemented in the form of asocket for accommodating an external card, such as SubscriberIdentification Module (SIM), User Identity Module (UIM), or a memorycard for information storage.

The second camera 121 b is shown located at the rear side of theterminal body and includes an image capturing direction that issubstantially opposite to the image capturing direction of the firstcamera unit 121 a. If desired, second camera 121 a may alternatively belocated at other locations, or made to be moveable, in order to have adifferent image capturing direction from that which is shown.

The second camera 121 b can include a plurality of lenses arranged alongat least one line. The plurality of lenses may also be arranged in amatrix configuration. The cameras may be referred to as an “arraycamera.” When the second camera 121 b is implemented as an array camera,images may be captured in various manners using the plurality of lensesand images with better qualities.

As shown in FIG. 1C, a flash 124 is shown adjacent to the second camera121 b. When an image of a subject is captured with the camera 121 b, theflash 124 may illuminate the subject.

As shown in FIG. 1B, the second audio output module 152 b can be locatedon the terminal body. The second audio output module 152 b may implementstereophonic sound functions in conjunction with the first audio outputmodule 152 a, and may be also used for implementing a speaker phone modefor call communication.

At least one antenna for wireless communication may be located on theterminal body. The antenna may be installed in the terminal body orformed by the case. For example, an antenna which configures a part ofthe broadcast receiving module 111 may be retractable into the terminalbody. Alternatively, an antenna may be formed using a film attached toan inner surface of the rear cover 103, or a case that includes aconductive material.

A power supply unit 190 for supplying power to the mobile terminal 100may include a battery 191, which is mounted in the terminal body ordetachably coupled to an outside of the terminal body. The battery 191may receive power via a power source cable connected to the interfaceunit 160. Also, the battery 191 can be recharged in a wireless mannerusing a wireless charger. Wireless charging may be implemented bymagnetic induction or electromagnetic resonance.

The rear cover 103 is shown coupled to the rear case 102 for shieldingthe battery 191, to prevent separation of the battery 191, and toprotect the battery 191 from an external impact or from foreignmaterial. When the battery 191 is detachable from the terminal body, therear case 103 may be detachably coupled to the rear case 102.

An accessory for protecting an appearance or assisting or extending thefunctions of the mobile terminal 100 can also be provided on the mobileterminal 100. As one example of an accessory, a cover or pouch forcovering or accommodating at least one surface of the mobile terminal100 may be provided. The cover or pouch may cooperate with the displayunit 151 to extend the function of the mobile terminal 100. Anotherexample of the accessory is a touch pen for assisting or extending atouch input to a touch screen.

FIG. 2 is a conceptual view of a deformable mobile terminal according toan alternative embodiment of the present invention. In this figure,mobile terminal 200 is shown having display unit 251, which is a type ofdisplay that is deformable by an external force. This deformation, whichincludes display unit 251 and other components of mobile terminal 200,may include any of curving, bending, folding, twisting, rolling, andcombinations thereof. The deformable display unit 251 may also bereferred to as a “flexible display unit.” In some implementations, theflexible display unit 251 may include a general flexible display,electronic paper (also known as e-paper), and combinations thereof. Ingeneral, mobile terminal 200 may be configured to include features thatare the same or similar to that of mobile terminal 100 of FIGS. 1A-1C.

The flexible display of mobile terminal 200 is generally formed as alightweight, non-fragile display, which still exhibits characteristicsof a conventional flat panel display, but is instead fabricated on aflexible substrate which can be deformed as noted previously.

The term e-paper may be used to refer to a display technology employingthe characteristic of a general ink, and is different from theconventional flat panel display in view of using reflected light.E-paper is generally understood as changing displayed information usinga twist ball or via electrophoresis using a capsule.

When in a state that the flexible display unit 251 is not deformed (forexample, in a state with an infinite radius of curvature and referred toas a first state), a display region of the flexible display unit 251includes a generally flat surface. When in a state that the flexibledisplay unit 251 is deformed from the first state by an external force(for example, a state with a finite radius of curvature and referred toas a second state), the display region may become a curved surface or abent surface. As illustrated, information displayed in the second statemay be visual information output on the curved surface. The visualinformation may be realized in such a manner that a light emission ofeach unit pixel (sub-pixel) arranged in a matrix configuration iscontrolled independently. The unit pixel denotes an elementary unit forrepresenting one color.

According to one alternative embodiment, the first state of the flexibledisplay unit 251 may be a curved state (for example, a state of beingcurved from up to down or from right to left), instead of being in flatstate. In this embodiment, when an external force is applied to theflexible display unit 251, the flexible display unit 251 may transitionto the second state such that the flexible display unit is deformed intothe flat state (or a less curved state) or into a more curved state.

If desired, the flexible display unit 251 may implement a flexible touchscreen using a touch sensor in combination with the display. When atouch is received at the flexible touch screen, the controller 180 canexecute certain control corresponding to the touch input. In general,the flexible touch screen is configured to sense touch and other inputwhile in both the first and second states.

One option is to configure the mobile terminal 200 to include adeformation sensor which senses the deforming of the flexible displayunit 251. The deformation sensor may be included in the sensing unit140.

The deformation sensor may be located in the flexible display unit 251or the case 201 to sense information related to the deforming of theflexible display unit 251. Examples of such information related to thedeforming of the flexible display unit 251 may be a deformed direction,a deformed degree, a deformed position, a deformed amount of time, anacceleration that the deformed flexible display unit 251 is restored,and the like. Other possibilities include most any type of informationwhich can be sensed in response to the curving of the flexible displayunit or sensed while the flexible display unit 251 is transitioninginto, or existing in, the first and second states.

In some embodiments, controller 180 or other component can changeinformation displayed on the flexible display unit 251, or generate acontrol signal for controlling a function of the mobile terminal 200,based on the information related to the deforming of the flexibledisplay unit 251. Such information is typically sensed by thedeformation sensor.

The mobile terminal 200 is shown having a case 201 for accommodating theflexible display unit 251. The case 201 can be deformable together withthe flexible display unit 251, taking into account the characteristicsof the flexible display unit 251.

A battery (not shown in this figure) located in the mobile terminal 200may also be deformable in cooperation with the flexible display unit261, taking into account the characteristic of the flexible display unit251. One technique to implement such a battery is to use a stack andfolding method of stacking battery cells.

The deformation of the flexible display unit 251 not limited to performby an external force. For example, the flexible display unit 251 can bedeformed into the second state from the first state by a user command,application command, or the like.

In accordance with still further embodiments, a mobile terminal may beconfigured as a device which is wearable on a human body. Such devicesgo beyond the usual technique of a user grasping the mobile terminalusing their hand. Examples of the wearable device include a smart watch,a smart glass, a head mounted display (HMD), and the like.

A typical wearable device can exchange data with (or cooperate with)another mobile terminal 100. In such a device, the wearable devicegenerally has functionality that is less than the cooperating mobileterminal. For instance, the short-range communication module 114 of amobile terminal 100 may sense or recognize a wearable device that isnear-enough to communicate with the mobile terminal. In addition, whenthe sensed wearable device is a device which is authenticated tocommunicate with the mobile terminal 100, the controller 180 maytransmit data processed in the mobile terminal 100 to the wearabledevice via the short-range communication module 114, for example. Hence,a user of the wearable device can use the data processed in the mobileterminal 100 on the wearable device. For example, when a call isreceived in the mobile terminal 100, the user can answer the call usingthe wearable device. Also, when a message is received in the mobileterminal 100, the user can check the received message using the wearabledevice.

FIG. 3 is a perspective view illustrating one example of a watch-typemobile terminal 300 in accordance with another exemplary embodiment. Asillustrated in FIG. 3, the watch-type mobile terminal 300 includes amain body 301 with a display unit 351 and a band 302 connected to themain body 301 to be wearable on a wrist. In general, mobile terminal 300may be configured to include features that are the same or similar tothat of mobile terminal 100 of FIGS. 1A-1C.

The main body 301 may include a case having a certain appearance. Asillustrated, the case may include a first case 301 a and a second case301 b cooperatively defining an inner space for accommodating variouselectronic components. Other configurations are possible. For instance,a single case may alternatively be implemented, with such a case beingconfigured to define the inner space, thereby implementing a mobileterminal 300 with a uni-body.

The watch-type mobile terminal 300 can perform wireless communication,and an antenna for the wireless communication can be installed in themain body 301. The antenna may extend its function using the case. Forexample, a case including a conductive material may be electricallyconnected to the antenna to extend a ground area or a radiation area.

The display unit 351 is shown located at the front side of the main body301 so that displayed information is viewable to a user. In someembodiments, the display unit 351 includes a touch sensor so that thedisplay unit can function as a touch screen. As illustrated, window 351a is positioned on the first case 301 a to form a front surface of theterminal body together with the first case 301 a.

The illustrated embodiment includes audio output module 352, a camera321, a microphone 322, and a user input unit 323 positioned on the mainbody 301. When the display unit 351 is implemented as a touch screen,additional function keys may be minimized or eliminated. For example,when the touch screen is implemented, the user input unit 323 may beomitted.

The band 302 is commonly worn on the user's wrist and may be made of aflexible material for facilitating wearing of the device. As oneexample, the band 302 may be made of fur, rubber, silicon, syntheticresin, or the like. The band 302 may also be configured to be detachablefrom the main body 301. Accordingly, the band 302 may be replaceablewith various types of bands according to a user's preference.

In one configuration, the band 302 may be used for extending theperformance of the antenna. For example, the band may include therein aground extending portion (not shown) electrically connected to theantenna to extend a ground area.

The band 302 may include fastener 302 a. The fastener 302 a may beimplemented into a buckle type, a snap-fit hook structure, a Velcro®type, or the like, and include a flexible section or material. Thedrawing illustrates an example that the fastener 302 a is implementedusing a buckle.

FIG. 4 is a perspective view illustrating one example of a glass-typemobile terminal 400 according to another exemplary embodiment. Theglass-type mobile terminal 400 can be wearable on a head of a human bodyand provided with a frame (case, housing, etc.) therefor. The frame maybe made of a flexible material to be easily worn. The frame of mobileterminal 400 is shown having a first frame 401 and a second frame 402,which can be made of the same or different materials. In general, mobileterminal 400 may be configured to include features that are the same orsimilar to that of mobile terminal 100 of FIGS. 1A-1C.

The frame may be supported on the head and defines a space for mountingvarious components. As illustrated, electronic components, such as acontrol module 480, an audio output module 452, and the like, may bemounted to the frame part. Also, a lens 403 for covering either or bothof the left and right eyes may be detachably coupled to the frame part.

The control module 480 controls various electronic components disposedin the mobile terminal 400. The control module 480 may be understood asa component corresponding to the aforementioned controller 180. FIG. 4illustrates that the control module 480 is installed in the frame parton one side of the head, but other locations are possible.

The display unit 451 may be implemented as a head mounted display (HMD).The HMD refers to display techniques by which a display is mounted to ahead to show an image directly in front of a user's eyes. In order toprovide an image directly in front of the user's eyes when the userwears the glass-type mobile terminal 400, the display unit 451 may belocated to correspond to either or both of the left and right eyes. FIG.4 illustrates that the display unit 451 is located on a portioncorresponding to the right eye to output an image viewable by the user'sright eye.

The display unit 451 may project an image into the user's eye using aprism. Also, the prism may be formed from optically transparent materialsuch that the user can view both the projected image and a generalvisual field (a range that the user views through the eyes) in front ofthe user.

In such a manner, the image output through the display unit 451 may beviewed while overlapping with the general visual field. The mobileterminal 400 may provide an augmented reality (AR) by overlaying avirtual image on a realistic image or background using the display.

The camera 421 may be located adjacent to either or both of the left andright eyes to capture an image. Since the camera 421 is located adjacentto the eye, the camera 421 can acquire a scene that the user iscurrently viewing. The camera 421 may be positioned at most any locationof the mobile terminal. In some embodiments, multiple cameras 421 may beutilized. Such multiple cameras 421 may be used to acquire astereoscopic image.

The glass-type mobile terminal 400 may include user input units 423 aand 423 b, which can each be manipulated by the user to provide aninput. The user input units 423 a and 423 b may employ techniques whichpermit input via a tactile input. Typical tactile inputs include atouch, push, or the like. The user input units 423 a and 423 b are shownoperable in a pushing manner and a touching manner as they are locatedon the frame part and the control module 480, respectively.

If desired, mobile terminal 400 may include a microphone which processesinput sound into electric audio data, and an audio output module 452 foroutputting audio. The audio output module 452 may be configured toproduce audio in a general audio output manner or an osteoconductivemanner. When the audio output module 452 is implemented in theosteoconductive manner, the audio output module 452 may be closelyadhered to the head when the user wears the mobile terminal 400 andvibrate the user's skull to transfer sounds.

A communication system which is operable with the variously describedmobile terminals will now be described in more detail. Such acommunication system may be configured to utilize any of a variety ofdifferent air interfaces and/or physical layers. Examples of such airinterfaces utilized by the communication system include FrequencyDivision Multiple Access (FDMA), Time Division Multiple Access (TDMA),Code Division Multiple Access (CDMA), Universal MobileTelecommunications System (UMTS) (including, Long Term Evolution (LTE),LTE-A (Long Term Evolution-Advanced)), Global System for MobileCommunications (GSM), and the like.

By way of a non-limiting example only, further description will relateto a CDMA communication system, but such teachings apply equally toother system types including a CDMA wireless communication system aswell as OFDM (Orthogonal Frequency Division Multiplexing) wirelesscommunication system. A CDMA wireless communication system generallyincludes one or more mobile terminals (MT or User Equipment, UE) 100,one or more base stations (BS s, NodeB, or evolved NodeB), one or morebase station controllers (BSCs), and a mobile switching center (MSC).The MSC is configured to interface with a conventional Public SwitchedTelephone Network (PSTN) and the BSCs. The BSCs are coupled to the basestations via backhaul lines. The backhaul lines may be configured inaccordance with any of several known interfaces including, for example,E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. Hence, theplurality of BSCs can be included in the CDMA wireless communicationsystem.

Each base station may include one or more sectors, each sector having anomni-directional antenna or an antenna pointed in a particular directionradially away from the base station. Alternatively, each sector mayinclude two or more different antennas. Each base station may beconfigured to support a plurality of frequency assignments, with eachfrequency assignment having a particular spectrum (e.g., 1.25 MHz, 5MHz, etc.).

The intersection of sector and frequency assignment may be referred toas a CDMA channel. The base stations may also be referred to as BaseStation Transceiver Subsystems (BTSs). In some cases, the term “basestation” may be used to refer collectively to a BSC, and one or morebase stations. The base stations may also be denoted as “cell sites.”Alternatively, individual sectors of a given base station may bereferred to as cell sites.

A broadcasting transmitter (BT) transmits a broadcast signal to themobile terminals 100 operating within the system. The broadcastreceiving module 111 of FIG. 1A is typically configured inside themobile terminal 100 to receive broadcast signals transmitted by the BT.

Global Positioning System (GPS) satellites for locating the position ofthe mobile terminal 100, for example, may cooperate with the CDMAwireless communication system. Useful position information may beobtained with greater or fewer satellites than two satellites. It is tobe appreciated that other types of position detection technology, (i.e.,location technology that may be used in addition to or instead of GPSlocation technology) may alternatively be implemented. If desired, atleast one of the GPS satellites may alternatively or additionally beconfigured to provide satellite DMB transmissions.

The location information module 115 is generally configured to detect,calculate, or otherwise identify a position of the mobile terminal. Asan example, the location information module 115 may include a GlobalPosition System (GPS) module, a Wi-Fi module, or both. If desired, thelocation information module 115 may alternatively or additionallyfunction with any of the other modules of the wireless communicationunit 110 to obtain data related to the position of the mobile terminal.

A typical GPS module 115 can measure an accurate time and distance fromthree or more satellites, and accurately calculate a current location ofthe mobile terminal according to trigonometry based on the measured timeand distances. A method of acquiring distance and time information fromthree satellites and performing error correction with a single satellitemay be used. In particular, the GPS module may acquire an accurate timetogether with three-dimensional speed information as well as thelocation of the latitude, longitude and altitude values from thelocation information received from the satellites.

Furthermore, the GPS module can acquire speed information in real timeto calculate a current position. Sometimes, accuracy of a measuredposition may be compromised when the mobile terminal is located in ablind spot of satellite signals, such as being located in an indoorspace. In order to minimize the effect of such blind spots, analternative or supplemental location technique, such as Wi-FiPositioning System (WPS), may be utilized.

The Wi-Fi positioning system (WPS) refers to a location determinationtechnology based on a wireless local area network (WLAN) using Wi-Fi asa technology for tracking the location of the mobile terminal 100. Thistechnology typically includes the use of a Wi-Fi module in the mobileterminal 100 and a wireless access point for communicating with theWi-Fi module.

The Wi-Fi positioning system may include a Wi-Fi location determinationserver, a mobile terminal, a wireless access point (AP) connected to themobile terminal, and a database stored with wireless AP information.

The mobile terminal connected to the wireless AP may transmit a locationinformation request message to the Wi-Fi location determination server.The Wi-Fi location determination server extracts the information of thewireless AP connected to the mobile terminal 100, based on the locationinformation request message (or signal) of the mobile terminal 100. Theinformation of the wireless AP may be transmitted to the Wi-Fi locationdetermination server through the mobile terminal 100, or may betransmitted to the Wi-Fi location determination server from the wirelessAP.

The information of the wireless AP extracted based on the locationinformation request message of the mobile terminal 100 may include oneor more of media access control (MAC) address, service setidentification (SSID), received signal strength indicator (RSSI),reference signal received Power (RSRP), reference signal receivedquality (RSRQ), channel information, privacy, network type, signalstrength, noise strength, and the like.

The Wi-Fi location determination server may receive the information ofthe wireless AP connected to the mobile terminal 100 as described above,and may extract wireless AP information corresponding to the wireless APconnected to the mobile terminal from the pre-established database. Theinformation of any wireless APs stored in the database may beinformation such as MAC address, SSID, RSSI, channel information,privacy, network type, latitude and longitude coordinate, building atwhich the wireless AP is located, floor number, detailed indoor locationinformation (GPS coordinate available), AP owner's address, phonenumber, and the like. In order to remove wireless APs provided using amobile AP or an illegal MAC address during a location determiningprocess, the Wi-Fi location determination server may extract only apredetermined number of wireless AP information in order of high RSSI.

Then, the Wi-Fi location determination server may extract (analyze)location information of the mobile terminal 100 using at least onewireless AP information extracted from the database.

A method for extracting (analyzing) location information of the mobileterminal 100 may include a Cell-ID method, a fingerprint method, atrigonometry method, a landmark method, and the like.

The Cell-ID method is used to determine a position of a wireless APhaving the largest signal strength, among peripheral wireless APinformation collected by a mobile terminal, as a position of the mobileterminal. The Cell-ID method is an implementation that is minimallycomplex, does not require additional costs, and location information canbe rapidly acquired. However, in the Cell-ID method, the precision ofpositioning may fall below a desired threshold when the installationdensity of wireless APs is low.

The fingerprint method is used to collect signal strength information byselecting a reference position from a service area, and to track aposition of a mobile terminal using the signal strength informationtransmitted from the mobile terminal based on the collected information.In order to use the fingerprint method, it is common for thecharacteristics of radio signals to be pre-stored in the form of adatabase.

The trigonometry method is used to calculate a position of a mobileterminal based on a distance between coordinates of at least threewireless APs and the mobile terminal. In order to measure the distancebetween the mobile terminal and the wireless APs, signal strength may beconverted into distance information, Time of Arrival (ToA), TimeDifference of Arrival (TDoA), Angle of Arrival (AoA), or the like may betaken for transmitted wireless signals.

The landmark method is used to measure a position of a mobile terminalusing a known landmark transmitter.

In addition to these position location methods, various algorithms maybe used to extract (analyze) location information of a mobile terminal.Such extracted location information may be transmitted to the mobileterminal 100 through the Wi-Fi location determination server, therebyacquiring location information of the mobile terminal 100.

The mobile terminal 100 can acquire location information by beingconnected to at least one wireless AP. The number of wireless APsrequired to acquire location information of the mobile terminal 100 maybe variously changed according to a wireless communication environmentwithin which the mobile terminal 100 is positioned.

As previously described with regard to FIG. 1A, the mobile terminal maybe configured to include short-range communication techniques such asBluetooth™, Radio Frequency Identification (RFID), Infrared DataAssociation (IrDA), Ultra Wideband (UWB), ZigBee, Near FieldCommunication (NFC), Wireless USB (Wireless Universal Serial Bus), andthe like.

A typical NFC module provided at the mobile terminal supportsshort-range wireless communication, which is a non-contactable type ofcommunication between mobile terminals and generally occurs within about10 cm. The NFC module may operate in one of a card mode, a reader mode,or a P2P mode. The mobile terminal 100 may further include a securitymodule for storing card information, in order to operate the NFC modulein a card mode. The security module may be a physical medium such asUniversal Integrated Circuit Card (UICC) (e.g., a SubscriberIdentification Module (SIM) or Universal SIM (USIM)), a secure micro SDand a sticker, or a logical medium (e.g., embedded Secure Element (SE))embedded in the mobile terminal. Single Wire Protocol (SWP)-based dataexchange may be performed between the NFC module and the securitymodule.

In a case where the NFC module operates in a card mode, the mobileterminal may transmit card information on a general IC card to theoutside. More specifically, if a mobile terminal having card informationon a payment card (e. g, a credit card or a bus card) approaches a cardreader, a short-range mobile payment may be executed. As anotherexample, if a mobile terminal which stores card information on anentrance card approaches an entrance card reader, an entrance approvalprocedure may start. A card such as a credit card, a traffic card, or anentrance card may be included in the security module in the form ofapplet, and the security module may store card information on the cardmounted therein. Card information for a payment card may include any ofa card number, a remaining amount and usage history, and the like. Cardinformation of an entrance card may include any of a user's name, auser's number (e.g., undergraduate number or staff number), an entrancehistory, and the like.

When the NFC module operates in a reader mode, the mobile terminal canread data from an external tag. The data received from the external tagby the mobile terminal may be coded into the NFC Data Exchange Formatdefined by the NFC Forum. The NFC Forum generally defines four recordtypes. More specifically, the NFC Forum defines four Record TypeDefinitions (RTDs) such as smart poster, text, Uniform ResourceIdentifier (URI), and general control. If the data received from theexternal tag is a smart poster type, the controller may execute abrowser (e.g., Internet browser). If the data received from the externaltag is a text type, the controller may execute a text viewer. If thedata received from the external tag is a URI type, the controller mayexecute a browser or originate a call. If the data received from theexternal tag is a general control type, the controller may execute aproper operation according to control content.

In some cases in which the NFC module operates in a P2P (Peer-to-Peer)mode, the mobile terminal can execute P2P communication with anothermobile terminal. In this case, Logical Link Control Protocol (LLCP) maybe applied to the P2P communication. For P2P communication, connectionmay be generated between the mobile terminal and another mobileterminal. This connection may be categorized as a connectionless modewhich ends after one packet is switched, and a connection-oriented modein which packets are switched consecutively. For a typical P2Pcommunication, data such as an electronic type name card, addressinformation, a digital photo and a URL, a setup parameter for Bluetoothconnection, Wi-Fi connection, etc. may be switched. The P2P mode can beeffectively utilized in switching data of a small capacity, because anavailable distance for NFC communication is relatively short.

Further preferred embodiments will be described in more detail withreference to additional drawing figures. It is understood by thoseskilled in the art that the present features can be embodied in severalforms without departing from the characteristics thereof.

Embodiments of the present invention explain a mobile terminal 100 shownin FIG. 1a to FIG. 1c for example. Yet, depending on an embodiment, amobile terminal explained by the embodiments of the present inventionmay correspond to one of a mobile terminal 200 shown in FIG. 2, a mobileterminal 300 shown in FIG. 3, and a mobile terminal 400 shown in FIG. 4.

Meanwhile, according to embodiments of the present invention describedin the following, when a user is talking on the phone using a mobiledevice, various functions of the mobile device can be automaticallyexecuted by simply operating a wearable device (e.g., a smart watch)without terminating the phone call.

According to a legacy technology, when a user is talking on the phoneusing a mobile device, since the user has one hand only for operating awearable device, it was difficult for the user to execute the wearabledevice. Moreover, when the user is talking on the phone using the mobiledevice, if the user intends to search for information such as calendar,telephone number or the like or input various memos and the like, theuser has no choice but to temporarily terminate the phone call.

In order to solve the aforementioned problem, according to embodiment ofthe present invention, a simple function (e.g., dial pad input,recording and the like) can be executed by utilizing a gesture of awearable device (e.g., smart watch) in the middle of talking on thephone using a mobile device. Moreover, phone call switching can benaturally performed in a manner of lowering a hand holding the mobiledevice and raising the smart watch to an ear. When a text message isreceived in the middle of talking on the phone using the mobile device,if the hand holding the mobile device is lowered and the smart watch israised to an ear, the mobile device is configured to automaticallyexecute a message-related application. By doing so, multitasking can beenabled while time of terminating a phone call is minimized.

FIG. 5 is a block diagram for main configuration elements of a mobiledevice and a wearable device according to one embodiment of the presentinvention. Yet, those skilled in the art can complementally interpret amobile device 520 depicted in FIG. 5 with reference to FIG. 1 to FIG. 2and can complementally interpret a wearable device 510 depicted in FIG.5 with reference to FIG. 3 to FIG. 4.

The wearable device 510 shown in FIG. 5 includes a memory 511, a displaymodule 512, a touch recognition module 513, a communication module 514configured to perform communication link with the mobile device 520 anda controller 515 configured to control the memory, the display module,the touch recognition module and the communication module.

In particular, the controller 515 is configured to receive dataindicating a call mode of the mobile device 520 from the mobile device520, configured to firstly sense a predetermined gesture, configured tosecondly sense a location change of at least one of the wearable device510 and the mobile device 520, configured to switch a mode of thewearable device 510 to a call mode and configured to transmit a commandfor making the mobile device 520 enter a specific mode instead of thecall mode to the mobile device 520.

For instance, the predetermined gesture consists of at least two or moregestures. The aforementioned different specific mode is changedaccording to a first gesture and the changed specific mode is fixedaccording to a second gesture. More specifically, an amount of anglechange of the second gesture is relatively greater than an amount ofangle change of the first gesture. Regarding this, it shall be describedlater in more detail with reference to FIG. 16 to FIG. 18 in thefollowing.

According to a different embodiment, the controller 515 is configured tosense a case that a location of the mobile device 520 is relativelycloser to the ground compared to a location of the wearable device 510.Regarding this, it shall be described later in more detail withreference to FIG. 7 and FIG. 8 in the following.

According to a further different embodiment, for instance, the differentspecific mode is stored in the memory 511 of the wearable device 510 inadvance or changes according to a user selection. Regarding this, itshall be described later in more detail with reference to FIG. 12 in thefollowing.

Meanwhile, the mobile device 520 shown in FIG. 5 includes a touchdetection sensor 521, a location detection sensor 524, a memory 525, adisplay module 526, a first communication module 522 configured toperform communication link with the wearable device 510, a secondcommunication module 523 configured to enter a call mode with anexternal mobile device and a controller 527 configured to control thetouch detection sensor, the location detection sensor, the memory, thedisplay module, the first communication module and the secondcommunication module.

In particular, the controller 527 is configured to sense a locationchange of at least one of the wearable device 510 and the mobile device520, configured to receive a command for making the mobile device 520enter a different specific mode instead of a call mode from the wearabledevice 510, and configured to control the mobile device to enter thespecific mode instead of the call mode.

The location detection sensor 524 further includes a proximity sensorconfigured to determine whether the mobile device 520 is separated froma face of a user more than a predetermined distance. Hence, an intentionof a user intending to forward a call function executed in the mobiledevice to the wearable device (watch) can be estimated via the proximitysensor.

According to a different embodiment, the location detection sensor 524is configured to sense a case that a location of the mobile device 520is relatively closer to the ground compared to a location of thewearable device 510. Regarding this, it shall be described later in moredetail with reference to FIG. 7 and FIG. 8 in the following.

According to a further different embodiment, the first communicationmodule 522 corresponds to a short range communication module and thesecond communication module 523 corresponds to a mobile communicationmodule.

FIG. 6 is a flowchart for operation orders of a mobile device and awearable device according to one embodiment of the present invention. Ofcourse, FIG. 6 can be complementally interpreted with reference to FIG.5.

A mobile device 600 establishes communication with a wearable device 610[S601]. For example, it may use Bluetooth and the like corresponding toshort range communication.

If the mobile device enters a call mode [S602], data indicating the callmode is transmitted to the wearable device [S603]. If the wearabledevice senses a specific gesture [S604], data indicating the specificgesture is transmitted back to the mobile device [S605]. The specificgesture used in the step S604 shall be described in FIG. 9 later.

A location change of at least one of the wearable device and the mobiledevice is sensed [S606, S607]. Subsequently, a sensed result is mutuallyforwarded to a counterpart device [S608]. The mobile device enters adifferent specific mode rather than the call mode [S610]. On thecontrary, the wearable device executes the call mode [S609].

Meanwhile, the step S606 to the step S608 shall be described in moredetail with reference to FIGS. 7 and 8 in the following.

Moreover, a data processing flow is summarized in terms of a wearabledevice shown in FIG. 6 in the following. The wearable device establishescommunication with a mobile device, receives data indicating a call modeof the mobile device from the mobile device and firstly senses apredetermined gesture. Subsequently, the wearable device secondly sensesa location change of at least one of the wearable device and the mobiledevice, switches a mode of the wearable device to a call mode after thesecond sensing and transmits a command for making the mobile deviceenter a different specific mode instead of the call mode to the mobiledevice. The command may vary according to a result of the first sensing.

FIGS. 7 and 8 are diagrams for a process for enabling a mobile deviceand a wearable device to switch a specific function according to oneembodiment of the present invention.

As pointed out above, according to one embodiment of the presentinvention, a mobile device can automatically execute a specific functionwithout terminating a phone call by an operation of changing a locationof a hand on which a smart watch corresponding to an example of awearable device is worn and a location of a hand holding the mobiledevice with each other.

As shown in FIG. 7, a random user is answering the phone using a mobiledevice 710 by one hand and a smart watch 720 corresponding to oneexample of a wearable device has no specific action. Yet, in this case,if the user intends to make a memo using the mobile device (whilemaintaining a currently connected phone call), according to a relatedart, the user has no choice but to temporarily terminate the phone call.

On the contrary, according to one embodiment of the present invention,as shown in FIG. 8 (compared to FIG. 7), if a mobile device 810 moves indown direction and a wearable device 820 moves in up direction, a modeof the wearable device 820 is automatically switched to a call mode.And, a user can manually select an application preferred by the user viathe mobile device 810. Of course, designing a predetermined function tobe automatically executed also belongs to the scope of the presentinvention. As mentioned in the foregoing description, the mobile deviceexecutes a different mode instead of the call mode and this can beconfigured via the wearable device. Regarding this, it shall bedescribed in detail with reference to FIG. 9 to FIG. 11 in thefollowing.

Meanwhile, although a location change of the mobile device and thewearable device is designed to be recognized as a command for switchinga call mode (executed by the wearable device instead of the mobiledevice) in FIG. 7 and FIG. 8, designing a different specific gestureinstead of the location change also belongs to the scope of the presentinvention.

FIGS. 9 to 11 are diagrams for an example of a process of automaticallyforwarding a call signal of a mobile device to a wearable deviceaccording to a specific condition.

As shown in FIG. 9, assume that a random user has both a mobile device920 and a wearable device 910 and data communication is establishedbetween the mobile device and the wearable device. In this case, if aspecific gesture (e.g., an operation of shaking the wearable device) isperformed using the wearable device 910 in a state that the mobiledevice 920 enters a call mode, it may enter a phone call helper mode.Such a terminology as a phone call helper mode used in the presentspecification corresponds to a mode that the call mode of the mobiledevice is switched to the wearable device and the mobile device executesa different specific function (e.g., memo, contact, etc.).

As mentioned earlier in FIG. 9, if a specific gesture is given to thewearable device 910, as shown in FIG. 10, it is able to select anapplication to be executed in the mobile device. For instance, thewearable device 1010 displays a first application 1011 at the center ofthe wearable device and displays a part of a second application 1012 atthe bottom of the wearable device. Yet, if a wrist snap gesture of auser wearing the wearable device is recognized, the wearable device 1020displays a part of the first application at the top of the wearabledevice, displays the second application at the center of the wearabledevice and displays a third application 1023 at the bottom of thewearable device. In particular, an application preferred by a user canbe selected using a snapping operation of a wrist.

Moreover, if an application intended to be executed in the mobile devicecorresponds to a second application 1022, the wearable device is raisedin up direction and the mobile device is lowered in down direction. Thismay correspond to a command for switching a mode of the wearable deviceinto a call mode and executing the selected second application 1022 inthe mobile device. Hence, as shown in FIG. 11, the mode of the wearabledevice is switched into the call mode. The call mode can be performedvia Bluetooth communication with the mobile device. Meanwhile, themobile device 120 executes the specific application 1022 selected inFIG. 10 instead of the call mode. In doing so, the call mode can beswitched to the wearable device by a simple gesture (of course, thescope of the present invention may be non-limited by the aforementionedup/down gesture and the up/down gesture can be replaced with a differentgesture) without terminating any phone call of the mobile device.

FIGS. 12 and 13 are diagrams for a process of switching a call mode of amobile device to a specific mode using a wearable device.

As shown in FIG. 12, when it is necessary to switch a call mode of amobile device into a different mode, a frequently used application canbe stored in a memory in advance. Of course, a user can separately add afrequently used application.

A user wearing the wearable device shown in FIG. 12 on a hand of theuser repeats snap until an application preferred by the user ispositioned at the center of the wearable device using a wrist snap1210/1211 of a small change amount. When the application preferred bythe user is positioned at the center, if the user performs a wrist snap1220 of a big change amount, the application is selected.

Assume that the mobile device is in the call mode. In this case, if themobile device is lowered in down direction and the wearable device israised in up direction, as shown in FIG. 13, the mobile device executesthe selected application 1320 instead of the call mode 1310. Moreover,although it is not depicted in FIG. 13, the wearable device shown inFIG. 12 is automatically switched to the call mode and a user cancontinuously maintain the phone call.

FIGS. 14 and 15 are diagrams for a different example of a process ofautomatically forwarding a call signal of a mobile device to a wearabledevice according to a specific condition.

If a text message is received in the middle of talking on the phoneusing a mobile device, the phone call should be temporarily terminatedto make a reply. A solution for the aforementioned problem is describedwith reference to FIG. 14 and FIG. 15 in the following.

As shown in FIG. 14, if a text message is received in a state that amobile device 1420 is in a call mode, a data interworking wearabledevice 1410 displays the text message. In this case, if the wearabledevice 1410 is raised in up direction (e.g., direction toward a face)and the mobile device 1420 is lowered in down direction, as shown inFIG. 15, the wearable device 1510 is configured to be switched to thecall mode (transmits and receives audio/video data to/from the mobiledevice via Bluetooth communication) and the mobile device 1520 isconfigured to terminate the call mode and automatically execute amessage application. Moreover, in consideration of a hand wearing thewearable device positioned at an upper side, displaying a virtualkeyboard appropriate for using a single hand also corresponds to onecharacteristic of the present invention.

FIGS. 16 to 18 are diagrams for a schematic process of controlling amobile device controlled by a wearable device according to a differentembodiment of the present invention.

In the foregoing drawings, it is explained as an applicationirrespective of a call mode can also be separately selected or added. Onthe contrary, a solution for easily selecting 6 menus (e.g., recoding,terminating, dial pad, speaker, mute, Bluetooth, etc.) displayed in thecall mode is explained in the following drawings.

As shown in FIG. 16, if a mobile device 1610 enters a call mode, arecording 1611, a terminating 1612, a dial pad 1613, a speaker 1614, amute 1615 and a Bluetooth 1616 menu are displayed in general. Yet,according to a related art, since the mobile device 1610 should betemporarily separated from an ear to select the menu, there is no choicebut to temporarily terminate the phone call. Yet, a user can enter aphone call helper mode by performing a specific gesture on the wearabledevice 1620.

In particular, as shown in FIG. 17, if a user lightly snaps 1721 thewearable device 1720 in one direction while maintaining the call mode,menus capable of being selected are sequentially displayed. In thiscase, the snap 1721 corresponds to about 30 degrees 1731, by which thepresent invention may be non-limited. For example, in FIG. 17, when auser intends to select a dial pad corresponding to a specific menuoutputted on the wearable device 1720, as shown in FIG. 18, if the userstrongly snaps 1821 the wearable device 1820 in one direction, it isrecognized as a currently displayed menu is selected. The mobile device1810 displays the selected dial pad 1811 in a manner of highlighting thedial pad and a screen of the wearable device is switched to a screendisplaying a corresponding function, i.e., a dial pad. In this case, thestrong snap 1821 corresponds to about 60 degrees 1831, by which thepresent invention may be non-limited. Moreover, although FIG. 16 to FIG.18 show examples of a snap gesture, the present invention can also beextensively applied to a different gesture.

FIG. 19 is a diagram for a specific gesture of a wearable deviceselecting a specific mode of a mobile device according to a differentembodiment of the present invention. The snap operation mentionedearlier in the foregoing drawings is explained in more detail withreference to FIG. 19 in the following.

As shown in FIG. 19, if a user snaps 1911 the wearable device 1910 inleft and right direction, a screen of the wearable device 1920 isswitched to a screen capable of selecting various menus corresponding toa phone call helper. Although the wearable device 1920 is currentlydisplaying a recording menu 1922, the remaining menus 1923/1924/1925 aresequentially displayed according to a light snap operation 1921. Inparticular, the user checks a plurality of menus one by one via thelight snap operation. If a menu preferred by the user is positioned atthe screen of the wearable device, the user can select the currentlydisplayed menu 1933 in a manner of giving a strong snap operation 1931to the mobile device 1930. Of course, it is also able to select othermenus 1932/1934/1935. Moreover, although it is not depicted in FIG. 19,it is able to prevent unnecessary battery consumption or data processingfrom being occurred in a manner of not displaying a selected menu on themobile device.

FIGS. 20 to 22 are diagrams for a process of a wearable device executinga first mode of a mobile device according to a different embodiment ofthe present invention. In this case, for example, the first mode maycorrespond to a “recording” function corresponding to one of menusprovided by a phone call helper.

As shown in FIG. 20, a mobile device 2010 has entered a call mode. Inthis case, a user, who is intending to control the mobile device 2010while the phone call is maintained, strongly snaps a wearable device2020.
